The unidentified flying object that came flying to Kuuga's side combines with the TryChaser 2000 and becomes Kuuga's new machine: TryGoram.

Yusuke survives the grip of death and defeats Unidentified Lifeform #26, mushroom-type monster Me-Ginoga-De, and to have his body looked over, together he and Ichijo visit Tsubaki.

Sakurako studies the letters drawn in blood that were left at the scene of Unidentified Lifeform murder cases, and tells Ichijo who has arrived in Nagano that those letters were originally of the Gurongi alphabet.

While Sakurako at Shinano University examines the characters for 'warrior' carved on the restored ruins, Yusuke and Sakurai's force are running about Tokyo after the appearance of Unidentified Lifeforms #3 Zu-Gooma-Gu and #43 Go-Zazaru-Ba.

In response to the Unidentified Lifeforms who are growing stronger one after another, the combined police force feels a growing sense of danger and tasks Hikari Enokida of the Police Science Division with making countermeasures.

Alain has turned Makoto into Necrom Specter and now has full control of him, calling him the "perfect friend". Takeru immediately denies this and promises to get Makoto back.

Igor, using a Gamma's special powers, has infiltrated a company building. Meanwhile, numerous objects have become drawings in the city. It seems that a new Gamma has appeared. Takeru locates it, transforms into Ghost, and attacks but the Gamma does something nobody could expect...

Kanon, wanting to save her brother, searches for Alain by herself.

Takeru tries to teach the Gazai Gamma the meaning of friendship, but must also deal with both Igor and Necrom Specter seeking to destroy the "incomplete" Gamma.

Takeru is now more resolute in bringing Makoto's body back from the Gamma world and Alain seems to have agreed to help. However, Akari is the one to stop them, stating that "It is not time yet." Akari senses that something is going through Alain's mind and is determined to find out more. Igor issues new orders to Bills and the Hikoki Gamma. Alain, irritated at the way Akari is seeing through him, goes to Fumi's takoyaki stall and Kanon is there. Suddenly, she falls unconscious. When Alain looks up, the sky is red.

In spite of Takeru defeating the Hikoki Gamma, the red sky continues expanding. Weakened after his battle with Jabel, Alain is suffering the same effects as Kanon from the red sky. Thanks to Akari, things are not going as he intends them to. Alain finds Akari concentrated on her work and approaches silently...

While Kanon's condition worsens, Takeru, along with Narita, Shibuya and Onari, go around the city looking for the origin of the red sky. Without any concrete pattern or direction, the group is left in confusion.

Alain has taken a big step by deciding to live as a human with Fumi's memory in his heart. He asks Takeru and Makoto for help. After many difficulties, their objective has unified and they can now fully join forces. Alain proposes destroying the gates that connect this world to the Gamma world. Still at doubt about the recent insight into people's memories he's been having, Takeru agrees to assist Alain.

In the Gamma world, Edith questions Adel: "What do you wish for?" Adel laughs this question off and uses his newfound power. As a consequence, many adults have become children around the city, Shibuya’s mother being one of them. The Daitenku Temple is filled with children and a familiar face makes an appearance.

Igarashi has called Takeru into the memories of past times. He finds out a truth that has been hidden for 10 years. The wishes and feelings of his father, Igarashi, Saionji and the Hermit resonate inside him. What could be beyond these strange changes Takeru is experiencing?!

Meanwhile, Shibuya is looking for his mother, who has escaped yet again. More and more adults are being turned into children. Society itself may spiral out of control. Everyone is running against the clock to solve the mysterious phenomenon the new Gammaizer has set in motion.

Gammaizer Gravity begins to attack alongside Gammaizer Fire, causing significant damage. Alain attempts to defeat Gammazier Fire with a kamikaze-like ability of the Necrom system to protect Takeru, but is knocked out of his transformation at the last moment. The unexpected happens when Gammaizer Gravity both defeats Ghost, and destroys his Ore Eyecon, causing him to vanish.

Takeru's absence saddens his friends and allies and while they discuss how to revive him, the Gammaizers reappear. Akari opens a portal to send them to another world, but the plan fails when they managed to escape and soundly defeat the other riders.

Akari and the others vow to not give up, and their resolve and emotions not only revive Takeru, but grant him the Mugen Eyecon. Takeru returns with new strength and destroys Gammaizers Gravity and Fire. Is this new power only a temporary halt to Takeru's death, and can it permanently destroy the Gammaizers?

The meeting between Adel, Alia, and Igor commence. At the beginning of the debate Igor gets a blow from Alia. While Adel "defeats" Alia when she changes into Dark Necrom, his strength is still not comparable with the Gammaizers. Takeru encounters a debate in the house of a Father and a daughter. After arguing they were attacked by a Gammaizer. The Gammaizer appeared to look weak compared to the previous but the soul of the father and daughter swapped bodies. Billy the Kid appears and enters the body of Kanon. Takeru works to help resolve problems between the father and daughter. The father turned out to have a new relationship with the fugitive known by Mayu the daughter. While the Dad was in the Gammaizer's body, Mayu in her Dad's body, and the Gammaizer in Mayu's body, can Takeru and the gang solve this mystery and find out what he's after?

In an effort to help Mayu and her Father - Shinichiro - Takeru and the others help Mayu to solve the source of a leak in her Father's workplace - which her Father's partner suspects is her Shinichiro...

Adel has connected to the Demia network and taken control of everyone with the intent of becoming a new world himself. In order to stop this, Takeru, Makoto, and Alain transform and face all the revived Gammaizers. In that moment, Takeru taps into Adel's childhood memories. What he sees surprises him...

Takeru believes he can stop Adel's rampage by connecting with him. He tries but Adel responds by ordering the Gammaizers to eliminate them all.

Everyone vows to do what they can while Takeru is invisible. Meanwhile, the Gammaizer want to evolve. They order Copy Makoto to study how humans convert feelings into power because Takeru is the key to everything. Takeru watches people get connected to the Demia network when suddenly he gets a headache from all the voices.

Seeking the teachings of Renge and Sabimaru who has sealed away a lot of Chemies, Houtarou and Rinne go to a certain professional wrestling Dojo with Renge and the others.

When Houtarou immediately tries to find a Chemie, he's attacked by gang-like men who are after the Dojo's land. However, Alchemy can't be used against ordinary people. In front of a confused Rinne and the others, Houtarou borrowed Renge cards and transformed into Gotchard! However this time, a powerful Malgam suddenly appears!

A mysterious man appears in front of Supana after tracking him. He changes into a Malgam before attacking the former and Houtarou. Supana then transforms into Valvarad and counters, and so does Houtarou into Gotchard, but the Malgam escapes after Valvarad's counterattacks.

However, the man, who is set on overthrowing Supana, kidnaps Rinne in front of Houtarou in order to lure his nemesis out.

Who on earth is this man? And why is he so obsessed with Supana!?

"Sabimaru-Senpai is gone."

Houtarou laments his immaturity and weaknesses in the face of fleeting, yet endless suffering. How can he help Sabimaru? Just then, Houtarou is invited by Kajiki to call out a UFO whose sighting has recently become more frequent.

Houtarou and his friends find a possibility to rescue Sabimaru by befriending UFO-X. However, the Three Dark Sisters and Sabimaru with the Dreadriver appear before them! Equip yourself with the Number 10 Chemy and Change to Super Gotchard now, Houtarou Ichinose!

"There's something I'd like to ask of you, Ichinose."

Houtaro is asked by Rinne, who has a thoughtful look on her face, to confide in him about a certain problem of hers. Just what exactly is on her mind?

Then the two are dispatched to the appearance of a new Level 10, X-Rex. Houtaro and Rinne attempt to tame it but encounter a little girl instead...

The raw power of Super Gotchard overwhelms Dread and gains an upper-hand, but Dread is capable of executing counterattacks, resulting in a back-and-forth battle.

Meanwhile, Lachesis approaches the daughter-father duo Sawa and Manabe. Rinne attempts to protect them but Atropos intervenes with her magical abilities.

"So you are powerless after all."

Rinne is robbed of her bodily freedom by the triumphant Atropos...?!
